MORRIS KARP, OF PASSAIC, NEW JERSEY, ASSIGNOR TO PASSAIC METAL WARECOMPANY, OF PASSAIC, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed April 2, 1912. Selial No. 688,023.

To all whom it may concern I Be it known that I, MORRIS KARP, a citizenof the United States, and resident of Passaic, in the county of Passaicand State of New Jersey, have invented certain new and usefulImprovements in Means for Applying Flux to Articles to be Soldered, ofwhich the following is a specification.

My invention has reference to applying soldering flux to articles to besoldered, and has particular reference to applying flux or acid to theends of tin cans and analogous articles, such as to the top and bottomthereof, preparatory to soldering the same.

In carrying out my invention I provide means for rotatively supporting acan or analogous article, a flux or acid bath beneath the can, a brushor roll to dip into the bath and to engage the can seam, and means foroperating said brush and to permit the latter to freely follow thecontour of the can body.

Reference is to be had to the accompanying drawings forming part hereof,wherein,

Figure 1 is a partly sectional front view of a machine embodying myinvention; Fig. 2 is a cross section thereof; Fig. 3is a plan view ofthe machine; Fig. 4 is an end view looking from the left in Fig. 1, andFig. 5 is a section substantially similar to Fig. 2,

showing parts in a different position.

Similar numerals of reference indicate corresponding parts in theseveral views.

At 1 is a suitable frame which may be supported upon a table or bench a.Said frame has bearings supporting a slidable spindle 2 provided at theinner end with a head 3 adapted to bear against the end of a can 4.Spindle 2 is shown provided with a loose pulley 5, and a drum or thelike 7. A spring 7 between pulley 5 and drum 7 normally separates them.Pulley 5eand drum 7 have coacting friction faces 5 7 6 indicates adriving belt on pulley -5. In line with spindle 2 is a spindle 8 havinga head 9 normally spaced from head 3 to engage can 4 at its end oppositehead 3. Spindle 8 is journaled in a block or head 10 slidably supportedupon' frame 1. For this purpose block or head 10 is shown carried byslide 11 supported in ways 12 on frame 1, whereby block 10 and head 9may be moved to the left in Fig. 1 to engage the end of a can, and tothe right to release the can. For this purpose I have shown a bell-cranklever 14, pivoted upon frame 1 at 15, and connected with a treadle 16. Ihave shown rod 17 con nected with a tube 17 receiving a rod 17 connectedwith treadle 16, and a spring 17 within said tube bearing at one endagainst *rocked to push head 9 against can 4, and

when the treadle is released head 9 is moved back from the can, spring18 raising the treadle and restoring the parts. At 19 is a catch adaptedto engage one or more projections 7 c on drum 7 to positively stop therotation of head 3 and can 4. Catch 19 is shown carried by a rod20-guided upon frame 1, and connected by link 21 and rod 22 with treadle16. A spring 23 serves normally to press catch 19 toward drum 7 whentreadle 16 is raised. The arrangement of the parts is such that whenhead 9 is moved back to release the can the catch 19 will engage aprojection 7 and stop the rotation of head 3 on the can, and when thetreadle is depressed catch 19 will be removed from projection 7 and head9 will be moved against can 4 that is placed between the heads 3 and 9.

Below heads 3 and 9 are one or more baths 25, adapted to containsoldering fluid, such as suitable flux or acid, and into such flux oracid rotative brushes or rolls 26 are adapted to dip and to be elevatedinto contact with the seams of the rotating can. Said brushes 26 may beof suitable stifi felt or other absorptive material, and are shownmounted to rotate upon spindles 27 carried by arms 28, the latter beingshown carried by rod 29 supported in brackets 30 upon frame 1, to causethe brushes 26 to be raised and lowered. Counter-weights 31 on arms 28serve normally to raise brushes 26 against can 4. Means are connectedwith treadle 16 to cause brushes 26 to dip into the flux or acid whenthe treadle is raised and to allow said brushes to rise andhave freemovement against the can when the treadle is lowered. For this purpose Ihave shown a transverse rod 32 adapted to bear beneath arms 28 beyondtheir pivotal support 29, rod 32 being shown connected with an upwardlyextending bar 33 shown pivotally connected at its lower end to treadle16 by the pivot 34:. Bar 33 is shown guided for vertical movement by theguide. 35 shown projecting from table a. Bar 33 is shown provided'withspaced holes 33 adapted to receive rod 32 in different positions ofelevation to accommodate cans of different sizes.

The operation may be described as follows: With the parts in the normalpositions shown in Figs. 1 and 5, head 9 will be drawn to one side topermit the insertion of can 4 between heads 3 and 9, and bar 33 will beelevated to cause rod 32 to tilt arms 28 so that the brushes 26 will dipinto the flux or acid (see Fig. 5), and catch 19 will stop the rotationof head 3. The can 1 is then inserted between heads 3 and 9, and treadle16 is depressed, whereupon head 9 will be pushed against the can and thelatter will thus be pushed against said head and will be rotativelysupported, and further downward movement of treadle 16 is permitted bythe compression of spring 17 when the head of rod 17 is drawn fartherdownwardly by treadle 16; catch 19 will then be released from projection7 and by the depression of treadle 16- rod 32 will be lowered andweights 31 will cause arms 28 to tilt and raise the brushes 26 intoengagement with the seams of the can (see Fig. 2). When gage, therebyfrict-ionally uniting pulley 5 withdrum 7 and causing rotation of thelatter, head 3, can 1 and head 9. The rotation of the can in contactwith the brushes will cause the latter to apply flux or acid to the canseams and when treadle 16 is re leased catch 19 will rise and stop therotation of drum 7 and the can by engaging a projection 7 of said drum,the attendant will grasp the can, head 9 will move back from the can,and the raising of bar 33 causes the insertion of brushes 26 in the fluxor acid ready for another operation, and so on. As arms 28 are free torock above rod 32, it will be understood that cans of varying polygonalshape may rotate in contact with the brushes 26, arms 28 rocking toaccommodate such action as required. Also, cans of circular shape willrotate in contact with brushes 26 to apply flux or acid tothe cans.

Changes may be made in the details of construction shown and described,within the scope of the appended claims, without departing from thespirit of the invention. By the term can herein I mean any article towhich the flux is to be applied.

Having now described my invention what I claim is c 1. The combinationof means to rotatively support a can, a bath below the said means, anarm mounted to be tilted and provided with a brush adapted to dip intothe bath, a bar having means beneath the arm and otherwise disconnectedtherefrom to tilt the arm to dip the brush into the bath when the bar israised and to leave the arm free to rock when the bar is lowered tocause contact of the brush with the can when the latter rotates.
